This Sunday, AMC will premiere the first episode of the eagerly awaited zombie spinoff series "Fear the Walking Dead." And in an effort to drum up some excitement, the network has released the first three minutes of the opener, which offers viewers a quick introduction of a newly zombie-infected woman, named Gloria (played by Lexi Johnson), who might possibly be patient zero -- the first infected victim who started the zombie outbreak on the west coast.

Set in Los Angeles, the series acts as a companion piece, and sort-of prequel to the Robert Kirkman-created hit show "The Walking Dead." The new series, which centers on an LA family trying to flee the city when the zombie apocalypse first strikes, stars Kim Dickens, Cliff Curtis, Alycia Debnam-Carey, Frank Dillane, Lorenzo James Henrie, Elizabeth Rodriguez and Ruben Blades.

"Fear the Walking Dead" is set to air on Sunday, August 23rd.

synopsis: What did the world look like as it was transforming into the horrifying apocalypse depicted in "The Walking Dead"? This spin-off set in Los Angeles, following new characters as they face the beginning of the end of the world, will answer that question.
